Pokemon Platinum: How to Move the Boulder at Mount Coronet
Q: There is a giant boulder at Mt. Coronet that I can’t get past in Pokemon Platinum, how do I move it?
A: To move the boulder at Mt. Coronet, and any other boulder for that matter, you have to have the pokemon move HM Strength. You can’t use it until after you beat the sixth pokemon gym though, and it’s obtained from Riley at the top of the Lost Tower on Iron Island.
